Description: A ray is an infinite line used in raycasting to detect intersections with objects. In the context of programming and computer graphics, raycasting is a fundamental technique that simulates how light behaves in a three-dimensional environment. A ray can be imagined as a line extending from an origin point in a specific direction, and its main function is to determine if it intersects with any objects in its path. This intersection can be used for various purposes, such as collision detection, scene lighting, or creating visual effects. Rays are essential in many game engines and graphics applications, where they allow developers to implement complex mechanics such as shooting, object visibility, and navigation. The precision and efficiency in handling rays are crucial for achieving a smooth and realistic user experience, as they directly affect interaction with the virtual environment. Additionally, rays can be used in combination with other graphical techniques to enhance the visual quality of applications, such as ray tracing, which simulates light behavior more realistically.
